31. Trichanthecium parvifolium (Lam.) Zuloaga & Morrone   in Syst. Bot. Monogr. 94: 59. 2011.

Panicum parvifolium Lam., Tabl. Encycl.   1: 173. 1791.

Holotypus: SOUTH AMERICA: “Ex America merid.”, s.d., Richard s.n. (P-LA image seen; iso-: US [ US 00139840] image seen)   .

Creeping stoloniferous perennial, branching and rooting at nodes, to 1 m long, the culms and nodes glabrous. Leaf sheaths glabrous. Ligule a membrane. Leaf blades lanceolate to narrowly ovate, flat, chartaceous, broad and amplexicaul at base, 1.5–3 × 0.2–0.7 cm, glaucous, drying yellow-green, mostly appressed to the stem, often becoming reflexed at maturity, glabrous on both sides, or with a few long cilia near the ligule. Panicles terminal, the uppermost leaf blade usually partly covering the panicle, or shortly exserted, 1–3 cm long, ovate, the branches spreading or slightly reflexed, glabrous. Spikelets ovate to elliptic, apically obtuse, 1–2 mm long, green, never gaping open. Lower glume ½–2/3 as long as the spikelet, chartaceous, apically obtuse, 3– 5-veined, glabrous. Upper glume as long as the spikelet, herbaceous, 5-veined, glabrous. Lower floret barren, with a fully developed palea. Lower lemma herbaceous, 5-veined, glabrous. Upper lemma smooth, shiny, pale.

Distribution and ecology. – Common across Africa and South America. In damp shaded locations across most of Madagascar, absent from the southwest, 0–1500 m ( Fig. 16B View Fig ).

Notes. – Common understory plant. Can be recognised by the characteristic shape of the plant: short appressed leaves on the apical part of the culms partly covering the spreading panicle branches.

This species is illustrated by BOSSER (1969: Fig. 124f-j) and by ZULOAGA et al. (2011: Fig. 26).
